Item	Diets1			SEM	P-value
	Control	LL	SL
ALB, g/L	34.57	34.17	37.16	0.937	0.384
BUN, mmol/L	3.27a	3.43a	2.19b	0.389	<0.001
GLU, mmol/L	8.03a	7.40ab	7.14b	0.264	0.096
TG, mmol/L	0.550	0.572	0.488	0.025	0.628
TP, g/L	48.86	49.25	44.74	1.443	0.209

SEM = standard error of the mean; ALB = albumin; BUN = blood urea nitrogen; GLU = glucose; TG = triglyceride; TP = Total phosphorus.

^{a, b} Different letters within a row indicate significant differences at P < 0.05.

¹Control, a normal protein containing 20% CP; LL, a low ratio of Lys to CP diet containing 17% CP; SL, a standard ratio of Lys to CP diet containing 17% CP; number of observation is 8.
